Abstract

Securing a screw to a shockmount to hinder loosening upon vibration is performed by a specially formed and secured piece of wire that rests, under exertion of spring force, in the screwdriver slot of the screw. Shown in the figure is a shockmount 1 mounted onto standoff bosses 2 to the base 3 of a casing 4. Shockmount 1 is fastened to base 3 with the help of screws 5. Shockmount 1 has a screw 6 that is free to rotate about its center axis. A bracket 7 contains a tapped hole 8 through which screw 6 passes. This allows vertical adjustment and fixing of bracket 7 relative to base 3 of casing 4. To prevent loosening of screw 6 out of hole 8, a formed piece of wire 9 is provided. One end 10 of that wire is fixed by screw 5 to retain it from rotation.

Torsion Shockmount Lock

Securing a screw to a shockmount to hinder loosening upon vibration is performed by a specially formed and secured piece of wire that rests, under exertion of spring force, in the screwdriver slot of the screw. Shown in the figure is a shockmount 1 mounted onto standoff bosses 2 to the base 3 of a casing 4. Shockmount 1 is fastened to base 3 with the help of screws 5. Shockmount 1 has a screw 6 that is free to rotate about its center axis. A bracket 7 contains a tapped hole 8 through which screw 6 passes. This allows vertical adjustment and fixing of bracket 7 relative to base 3 of casing 4. To prevent loosening of screw 6 out of hole 8, a formed piece of wire 9 is provided. One end 10 of that wire is fixed by screw 5 to retain it from rotation. The other end 11 of wire 9 passes through the screwdriver slot 12 of screw 6 to hinder its rotation. This end 11 of wire piece 9 is forced down into the screw driver slot 12 by a spring 13 that is formed out of winding wire 9. Spring 13 serves to hold down arm 11. Arm 11 can easily be flexed out of the screw driver slot 12, and bracket 7 can be adjusted in its height and secured; then arm 11 can be replaced in slot 12 of screw 6.
